Diesel Particulate Filters (DPFs) can vary greatly. Sponsored by AP Emissions.
Jason Stahl discusses diesel fuel systems, and the ideal time to perform a regeneration cycle, if the vehicle is able to perform the procedure. Sponsored by Standard.
The Diesel Particulate Filter (DPF) is a ceramic brick with tiny passages that do two things. First, they trap the particulates or soot in the exhaust. Second, these passages create the surface area for the precious metal that helps to burn or break down the particulates. Think of it as a catalytic converter that traps and oxidizes particulates in the exhaust. But, the DPF regenerates in intervals rather than all the time like those found on gasoline vehicles.
The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tail pipe.
